Abstract

UN CHIP DE CIRCUITO INTEGRADO INCLUYE UN ELEMENTO DE MEMORIA (10) QUE ALMACENA DATOS SECRETOS, UNA CAPA DE MATERIAL OPACO (14) QUE ENCAPSULA EL CHIP Y MEDIOS (12) PARA ELIMINAR LOS DATOS SECRETOS DE LA MEMORIA EN EL CASO DE QUE EL MATERIAL DE ENCAPSULACION SE SEPARE DEL CHIP. LOS MEDIOS DE ELIMINACION COMPRENDEN UN CIRCUITO PROTECTOR ENCAPSULADO POR EL MATERIAL DE ENCAPSULACION Y ACOPLADO AL ELEMENTO DE MEMORIA. EL CIRCUITO PROTECTOR INCLUYE UN ELEMENTO SENSIBLE (42, 90, 110, 122) QUE PRESENTA UNA CARACTERISTICA DE CORRIENTE QUE PRODUCE UN CAMBIO DETECTABLE DESPUES DE SU EXPOSICION A LA LUZ; MEDIOS (16, 16A, 16B, 16C) PARA DETECTAR DICHO CAMBIO DE CORRIENTE CUANDO EL ELEMENTO SENSIBLE A LA LUZ SE EXPONE A LA LUZ; Y MEDIOS CONMUTADORES (18) ACOPLADOS AL ELEMENTO DE MEMORIA Y A LOS MEDIOS DETECTORES PARA PROVOCAR QUE LOS DATOS SECRETOS SEAN SACADOS DEL ELEMENTO DE MEMORIA EN RESPUESTA A DICHO CAMBIO DE CORRIENTE PRODUCIDO POR EL ELEMENTO SENSIBLE A LA LUZ CUANDO EL ELEMENTO SENSIBLE A LA LUZSE EXPONE A LA LUZ, DE TAL FORMA QUE CUANDO EL MATERIAL DE ENCAPSULACION SE SEPARA DEL CHIP, LOS DATOS SECRETOS SE ELIMINAN DEL ELEMENTO DE MEMORIA.
